Abstract:
The paper deals with utilization of active triangulation method for shape investigation of cutting inserts after wear. For measuring of cutting insert shape a method using the structured light (fringe projection) was used. As a measuring device the optical 3D scanner GOM ATOS II TripleScan SO was used. Cutting inserts with different shapes was measured. With the measurement method mentioned in the paper the accurate shape of the cutting insert can be captured. From the 3D model moreover it is possible to measure the geometrical properties as well as tool wear, plastical deformation, build-up-e

The pupal wing is a bilayered epithelium which is patterned into vein and intervein domains, and which secretes the cuticle of the adult wing.

They are also notorious as important and efficient vectors of several plant viral diseases.

The paper presents the results of work on changing the mass of closed gears by the example of a single-stage cylindrical gearbox. Two variants of the solution for the problem are considered. In the first variant, it is proposed to reduce the thickness of the walls of unloaded areas to the constructive minimum. The other solution involves the replacement of the unloaded areas of the gearbox housing with non-metallic inserts. To produce the inserts, ZELLAMID plastic is recommended. Both variants are based on the method of topological optimization of housing parts. The Fusion 360 software product

Abstract:
The problem of optimum porous infinite sliding bearings design with isothermal compressed lubricant is solved. The sliders and journal bearings with maximum load carrying capacity or maximum a lubricant film static stiffness in conditions of restriction on the lubricant flow rate through a pored insert are examined. The found optimum shapes of bearings depend on problem parameters, determining property of lubricant and insert, conditions of feed and lubricant flow rate through an insert. Besides the bearings shape a size and position of insert are determined. The optimum shape features are the

Abstract:
Enhancement of the natural and forced convection heat transfer has been the subject of numerous academic and industrial studies. Air blenders, mechanical agitators, and static mixers have been developed to increase the forced convection heat transfer rate in compressible and incompressible flows. Stationary inserts can be efficiently employed as heat transfer enhancement devices in the natural convection systems. Generally, a stationary heat transfer enhancement insert consists of a number of equal motionless segments, placed inside of a pipe in order to control flowing fluid streams. These de

Abstract:
Abstract This paper summarizes the effects of various types or numbers of critical-heat-flux (CHF)-enhancing inserts in tubular geometries. The impact of inserts on CHF is frequently expressed by an enhancement ratio K: the ratio of CHF with an insert to the CHF in a bare tube for the same local flow conditions. The impact on K of the following parameters was investigated: (i) fluid type (Freon-134a, water), (ii) axial spacing between inserts, (iii) shape of the insert, (iv) flow blockage of the insert, (v) number of similar/dissimilar insert planes upstream, and (vi) impact of flow conditions

Abstract:
A 24-inch-diameter x 0.75-inch-wall X70 low-carbon bainitic-steel pipe was evaluated to obtain an independent measurement of pipe properties and to examine metallurgical characteristics that may affect behavior in gas-transmission service. The steel from which the pipe was produced was processed using advanced steelmaking methods to insure cleanliness but apparently was not treated for sulfide shape control since no sour gas exposure in service was anticipated. Primary microalloying additions in this high manganese steel, other than columbium, were titanium and boron. Titanium was added to for

Abstract:
The place of protein in sub-Saharan Africa’s food system is changing rapidly, raising complex international development, global health and environmental sustainability issues. Despite substantial growth in the region’s livestock agriculture sector, protein consumption per capita remains low, and high levels of undernourishment persist. Meanwhile sub-Saharan Africa’s population is growing and urbanising rapidly, creating expectations that demand for protein will increase rapidly over the coming decades and triggering calls for further investment in the expansion and intensification of the regio

Abstract:
As Elfdalian edges closer to recognition in Sweden, it seems pertinent to inspect how the political discussion surrounding this question is shaped in parliament, amongst local advocates, and in government. Parties involved argue for or against recognition using different and sometimes mismatching discursive strategies. As such, disagreement arises around key concepts. For one, most of the parliamentary debate attempts to prove Elfdalian’s qualities as a language, a discussion obscured by the government’s vague terminology. Actors also contest the meaning of recognition. Governmental communicat

Abstract:
Antifreeze proteins (AFPs) allow biological organisms, including insects, fish, and plants, to survive in freezing temperatures. While in solution, AFPs impart cryoprotection by creating a thermal hysteresis (TH), imparting ice recrystallization inhibition (IRI), and providing dynamic ice shaping (DIS). To leverage these ice-modulating effects of AFPs in other scenarios, a range of icing assays were performed with AFPs to investigate how AFPs interact with ice formation when tethered to a surface. In this work, we studied ApAFP752, an AFP from the beetle Anatolica polita, and first investigate

Excavations to inspect buried piping are often costly and risk damaging other plant assets during the digging. Some utilities have used permanently installed guided wave sensors to monitor piping condition and reduce the excavations.

Understanding the state-of-the-art will enable utilities to effectively use guided wave structural health monitoring in support of their underground piping aging ma
